CarolPassos they are just 3 cms!! Try taking some power stretching classes, or yoga as someone said up there. Practise reaching everyday and maybe you can get to the 212cms!
I'm 1.60 mts tall and fortunately I can reach 212cms standing in tiptoes, and leaning on the wall really helps. Oh, and I do it with one hand at a time to stretch every morning or afternoon. Bear in mind that when we wake up in the morning we're usually 1 cm taller than at night because our spine has rested and expanded when sleeping. (Sleep well too!)
EK is usually strict with this requirement as it is for safety reasons so if even trying all these tricks doesn't help, I'm sorry but your chances are slim.... however I wish you best of luck!!!
